Although it is a general thing, several sets are set at the same time, but the core wobbly wobbly fluctuates, causing variations in the set position. A review of the manufacturer selection was necessary.

Purchased for work centering work on lathe. I thought that it was somewhat long, but as long as I used it with a dial gauge of 0.01 mm, it is somewhat better. Although it is a usage not in the item explanation, since there are also many people who actually use the same way of usage, I think that it can be added to the usage example.
